Sub frame for register fronts



Patented July 1, less arm FFICE WILLIAM THOMAS TRUAX, F BATTLE CREEK, MICHIGAN, ASSIGNOR T0 UNITED STATES REGISTER CO., OF BATTLE CREEK, MICHIGAN, A CORPORATION OF MICH- IGAN SUB FRAME FOR REGISTER FRONTS Application filed September 18,1928. Serial No. 306,705.

This invention relates to sub frames for register fronts, for admitting warm air into the rooms of buildings to heat the same in cold weather. More particularly and with a special object in View this invention has to do with the production and arrangement of an additional frame or wall upon the under side of a register front which is used to divide the stack head flange from the deflector of the register and to prevent said flange from interfering with the operation of the deflector of the register.

The special construction and arrangement of this invention is illustrated in the accompanying drawings, of which Fig. 1 repre sents a side view, substantially full size, of portions of the sub frame before it is bent or formed and attached upon the inner surface of a register front or grill. Fig. 2 is a vertical sect-ion of the members shown in Fig. 1 taken on the broken line 2-2 of Fig. 1. Fig. 3 shows a rear view of a register front having this invention applied thereto, and Fig. 4 is a vertical section taken on the broken line 44 of Fig. 3.

Throughout the drawings and description the same number is used to refer to the same part.

Considering the drawings, a register front 1, of any chosen pattern or size, has the usual open work 2, and tabs or tongues 3 spaced along the upper edge, with securing device 4 at the bottom which may be turned upon a pivot 5. The construction of the register front as such may be widely varied within the purview of this invention.

The sub frame, referred to as a whole by numeral 6, is a strip of metal originally straight, and having its upper edge portion 40 bent over to form a shed or flange 7 At one end of the strip there is an extension 8,

and next to the extension there is formed through the strip a vertical slot 9, and there is a notch 10 cut in the lower edge of the strip in line with the slot 9. The purpose of the aligned slot and notch is to lessen the rigidity of the metal strip in order that the extension 8 may be readily bent at an angle with the strip when the sub frame is formed to be applied to a register front.

As shown and indicated in Figs. 1 and 2 the strip 6 is marked off into apl'urality of portions, the first portion shown in Fig. 1 being demarcated from the adjoining portion by slot 11 cut through the flange 7 and the slot 12 cut through the body of the strip and in line with the slot 11. A notch 13 is stamped in the lower edge of the strip and the notch is also in the transverse line passing through'the slots 11 and 12. It is the purpose of the slots and the notch as previously stated to enable the straight strip to be readily and certainly bent at the required points to form it into the rectangular frame set forth in Fig. 3 and comprising the four portions marked a, 72, o and (Z. It will be understood that there may be any number of portions of the strip demarcated by the slots and notches for the purpose mentioned, depending upon the'shape of the 7s predetermined area desired to be encompassed or enclosed by the frame.

In Fig. 1 at the end of the strip will be noted the tip or tongue 14 which will be again mentioned.

In Fig. 3 are shown a number of spot weldings 15 by which the flange 7 of the sub frame 6 and the register front 1 are joined together. This invention is in no sense limited to spot welding, as other means of attachment may be readily substituted.

The deflector 16 with which the register is provided is shown in Fig. 4, and it is provided with the usual operating finger piece or handle 17.

The operation of this invention will best be understood from Figs. 3 and 4. The four portions of the flanged and slotted strip 6 are arranged in a frame shape, being bent at the slots and notches as stated, and by the to agency of which a very material saving in time and labor is attained in assembling the parts, and the frame is spot weldedto the register front as set forth. Now the deflector operates wholly within the frame, and no outside bent wall or flange of the heating pipe necessarily joined to the register can interfere with the deflector. Its movement is wholly within the sub frame and it is adequately guarded thereby. In the manna roe facture of heating appliances of this nature, it is of the utmost importance that the cost thereof in time and labor as well as in material be reduced to a proper minimum, superior quality being always regarded, and the special construction herein specified ac- (ciomp ishes the desired saving in an unusual e ee.

avin now described this invention, and explains the manner of its use, I claim A sub flan e for registers comprising a unitary meta strip having one edge bent to form a flange extending throu hout the length of the strip, the said strip having at one end an extension and an adjacent slotted portion whereby the extension may be bent with respect to the length of the strip, the saidstrip being demarcated lon 'tudinally into four portions by slots exten ing transversely of the said strip and flange, and the other and of the strip having a tongue adapted to engage the said slot adjacent to the said extension.

In testimony whereof I afiix my signature.

WILLIAM THOMAS TRUAX.
